In preparation for implementing the promise based version, separate out
the legacy call data from the filter.
There are two commits here, each representing one phase of this code
movement:
66676d398c moves `class RetryFilter` into
the header and the vtable name into that class, as this will be shared
code between the implementations
4c84f115ad then moves `class
RetryFilter::CallData` into `class RetryFilterLegacyCallData`, and moves
*that* into its own file
Doing so makes me less confused as to what I'm editing going forward.
No functionality should be affected.

In real services most of our time ends up in the `Read1()` function,
which populates one byte into the bit buffer.
Change this to read in as many as possible bytes at a time into that
buffer.
Additionally, generate all possible (to some depth) parser geometries,
and add a benchmark for them. Run that benchmark and select the best
geometry for decoding base64 strings (since this is the main use-case).
(gives about a 30% speed boost parsing base64 then huffman encoded
random binary strings)

Try again to get a trailers only signal through to the logging filter.
(this needs a change for non-chttp2 transports... I think we wait until
we have actual users using binary logging on non http2 transports to do
that work)

Adds experimental fork support to gRPC/Ruby
Works towards https://github.com/grpc/grpc/issues/8798 (see caveats for why this wasn't marked fixed yet)
Works towards https://github.com/grpc/grpc/issues/33578 (see caveats for why this wasn't marked fixed yet)
This leverages existing `pthread_atfork` based C-core support for
forking that python/php use, but there's a bit extra involved mainly
because gRPC/Ruby has additional background threads.
New tests under `src/ruby/end2end` show example usage.
Based on https://github.com/grpc/grpc/pull/33495
Caveats:
- Bidi streams are not yet supported (bidi streams spawn background
threads which are not yet fork safe)
- Servers not supported
- Only linux supported
tcp_posix_test is incorrectly assuming that all endpoint_writes with
timestamps enabled will be successfully traced. Remove the timestamps
checking related tests to prevent flakes when the test is enabled
internally.
Most of the time parsing succeeds, and only rarely do we see an error.
This change reduces the parse memento size from 120 bytes to 56 bytes.

Remove `src/ruby/ext/grpc/objs/` and strip `src/ruby/ext/grpc/libs/` in
ruby build dir to save some space.
This can reduce the grpc gem size from more than 1G to about 70~80M.
This only affects opt build, dbg build remains the same.
A proper fix maybe use the same makefile to build c-core and the
extension rather than building c-core when generating the extension
makefile.
fixes: https://github.com/grpc/grpc/issues/33412
I'd been adding the following stanza regularly to debug flakes/fuzz
failures:
```
Expect(1, CoreEnd2endTest::MaybePerformAction{[&](bool success) {
Crash(absl::StrCat(
"Unexpected completion of client side call: success=",
success ? "true" : "false", " status=", server_status.ToString(),
" initial_md=", server_initial_metadata.ToString()));
}});
```
it was helpful because it indicated why a call batch finished
successfully and helped quickly identify next steps.
It occurred to me however that this would better be done inside of the
framework, and for *all* ops that have outputs, so this PR does just
that. Any time a batch with an op that outputs information finishes
successfully but unexpectedly we now display those outputs in human
readable form in the error message.
Sample output:
```

expected:

```
The intuition here is that these strings may end up in the hpack table,
and then unnecessarily extend the lifetime of the read blocks.
Instead, take a copy of these short strings when we need to and allow
the incoming large memory object to be discarded.

PanCakes to the rescue!
We noticed that our 'sanity' test was going to fail, but we think we can
fix that automatically, so we put together this PR to do just that!

Noticed this failing on an internal cl due to deadline exceeded errors.

It introduces the following syntax:
The following would mark the experiment as broken on ios, false on
windows and debug on posix. If a platform is un-specified, the default
for that platform will be set to false. Refer to
test/core/experiments/fixtures/test_experiments_rollout.yaml for
examples which are tested.
- name: experiment_1
default:
ios: broken
windows: false
posix: debug
It also supports the already existing syntax and interprets it as just
specifying one default for all platforms.
Supported platform tags: ios, windows, posix
Similar to https://github.com/grpc/grpc/pull/33542.
Note that there's a ticket to automatically use the one specified in the
--server_image_canonical flag, but for now we just hardcode.

This adds a new channel argument `GRPC_ARG_DSCP` which allows users to
create classified gRPC streams with a
Differentiated Services Code Point (DSCP) marking on the IP frames.
The channel argument is handled on both clients and servers, but
currently only on posix based systems.
Fixes#17225
**Background**:
In addition to what is already described is #17225, when gRPC is used in
telco systems there is often a need to classify streams of importance.
There can be multiple hops between two endpoints (e.g. between 2 telecom
operators) and some streams that are more important than others (e.g.
emergency call related or similar). By marking the IP packets using DSCP
the aware routers can make a sound decision of the prioritization.
This PR propose to use DSCP as the configuration value since its common
for both IPv4/IPv6, an alternative would be to use a config name that
includes TOS and Traffic Class.
There might be more needed regarding documentation and end2end testing,
but there I need some advice.

- Change the `ResolverFactory::GetDefaultAuthority()` method to %-encode
the authority by default, so individual resolver impls don't need to
remember to do this.
- Remove the hack in the xds resolver for setting the authority to
everything after the last `/` character.
- Change the `unix`, `unix-abstract`, and `vsock` resolvers to use a
real authority instead of hard-coding to "localhost".
Adds a test for the experiments codegen. It updates the codegen to parse
test_experiments.yaml and test_experiments_rollouts.yaml files and
generate test_experiments.h and test_experiments.cc files along with an
experiments_test.cc file. The experiments test verifies the returned
value of IsExperimentEnabled with the expected value.
This PR does the following: for the TLS server credentials, stops
calling `SSL_CTX_set_client_CA_list` by default in
`ssl_transport_security.cc`, and gives users a knob to re-enable calling
this API.
## What does the `SSL_CTX_set_client_CA_list` API do?
When this API is called, a gRPC TLS server sends the following data in
the ServerHello: for each certificate in the server's trust bundle, the
CA name in the certificate.
This API does not change the set of certificates trusted by the server
in any way. Rather, it is just providing a hint to the client about what
client certificate should be sent to the server.
## Why are we removing the use of `SSL_CTX_set_client_CA_list` by
default for the TLS server credentials?
Removing the use of this API by default has 2 benefits:
1. Calling this API makes gRPC TLS unusable for servers with a
sufficiently large trust bundle. Indeed, if the server trust bundle is
too large, then the server will always fail to build the ServerHello.
2. Calling this API is introducing a huge amount of overhead (1000s of
bytes) to each ServerHello, so removing this feature will improve
connection establishment latency for all users of the TLS server
credentials.
More work on the dualstack backend design:
- Now that all petiole policies have been changed to delegate to
pick_first, outlier detection no longer needs to eject via the
subchannel's raw connectivity state; it can now eject only via the
health state. See #33340.
- This also removes the now-unnecessary hack to explicitly disable
outlier detection in pick_first. See #33336.
